Hss was a fail, it rounded the edge in seconds... Most effective way was beltgrinder to get the OD smaller, and a diskgrinder for the angle.
Tried my diegrinder but it didnt have enough torque so i switched to a cordless drill.
Best way was to turn the flapwheel the opposite direction to the grinders.
